Abstract

The present review revisits representative studies addressing the development of efficient Pd-based carbon-supported heterogeneous catalysts for two important reactions, namely, the production of hydrogen from formic acid and the hydrogenation of carbon dioxide into formic acid. The HCOOH-CO2 system is considered a promising couple for a hydrogen storage system involving an ideal carbon-neutral cycle. Significant advancements have been achieved in the catalysts designed to catalyze the dehydrogenation of formic acid under mild reaction conditions, while much effort is still needed to catalyze the challenging CO2 hydrogenation reaction. The design of Pd-based carbon-supported heterogeneous catalysts for these reactions encompasses both the modulation of the properties of the active phase (particle size, composition, and electronic properties) and the modification of the supports by means of the incorporation of nitrogen functional groups. These approaches are herein summarized to provide a compilation of the strategies followed in recent studies and to set the basis for a hydrogen storage system attained using the HCOOH-CO2 couple.

通过 HCOOH-CO2 偶联物实现的储氢系统：钯基碳支撑异质催化剂的最新进展

本综述回顾了针对甲酸制氢和二氧化碳加氢转化为甲酸这两个重要反应开发高效钯基碳支撑异相催化剂的代表性研究。HCOOH-CO2 系统被认为是涉及理想碳中和循环的储氢系统的一种有前途的耦合。在温和的反应条件下催化甲酸脱氢反应的催化剂已经取得了重大进展，但催化具有挑战性的二氧化碳加氢反应仍需不懈努力。设计用于这些反应的钯基碳支撑异相催化剂既包括调节活性相的特性（粒度、组成和电子特性），也包括通过加入氮官能团对支撑物进行改性。本文对这些方法进行了总结，对近期研究中采用的策略进行了汇编，并为利用 HCOOH-CO2 偶联剂实现氢储存系统奠定了基础。
